摘　　要：以导弹纵向通道为例,介绍了导弹的过载控制模型,研究了传统PI/角速度反馈控制、H_∞/混合灵敏度控制,并在大攻角情况下进行了仿真计算。通过比较,可得下面结论:对于传统PI/角速度反馈控制方法,其结构简单、工程上易于实现,但系统响应速度慢,鲁棒性较差;而H_∞/混合灵敏度控制方法,响应速度快,鲁棒性能较好,但控制器阶次较高,工程上较难实现。Consider pitch channel of missile as example, its overload control models are introduced, based on which, the following two design methods are studied: the conventional PI/angular velocity feedback control, and H_∞/mixed sensitivity control. Simulations with a bigger attacking angle are conducted. By comparing, the following conclusion can be obtained: the conventional PI/angular velocity feedback control is simple in structure and can be implemented easily, but the system response is slower and the robustness is poor; H_∞/mixed sensitivity control has stronger robustness, and the system response is faster, but the controller has higher order, which makes its implementation more difficult.
